The HomeGoods store in Terra Linda, which has been closed since its roof collapsed in October, is set to reopen on Sept. 8, the company said.

“We’re very excited,” said Stephen Logan, vice president of Northgate mall owner Merlone Geier Partners. HomeGoods, he said, has been “a very successful retailer for the site.”

The roof of the store, at 6000 Northgate Drive, partially caved in on the morning of Oct. 2 following a night of heavy rain. Both TJX Companies, the Massachusetts-based parent corporation of HomeGoods, and Merlone Geier Partners declined to comment on the cause of the collapse.

Don Jeppson, San Rafael’s chief building official, said it appears that a major connector between two wooden beams had decayed from dry rot and collapsed under the weight of rain that had pooled on the roof.

The collapse happened before the store was scheduled to open. Two employees who had arrived for their shift called the fire department after they noticed the ceiling was sagging and leaking.

Firefighters were preparing to go inside when the ceiling came crashing down near the front of the store. The employees were outside at the time. No injuries were reported, according to Jeppson.

Construction has been completed to repair the building, according to Logan. He wouldn’t disclose the extent of the damage or the cost of the repair.

“As part of the reconstruction, we did an extensive structural analysis of the entire building,” Logan said. “This was a very deliberate process that took a while longer than anticipated.”

The HomeGoods store, which sells home furnishings, occupies the nearly 30,000-square-foot building that used to house Rite Aid. The pharmacy has moved to a different location in the shopping center.
